I am pretty computer illiterate so if you need more info let me know but my computer has stopped recognizing that there is a cd in the d drive. when i go through my comp and d drive properties under hardware there is something listed as HDS722540VLAT20 that appears to be selected as the drive in use. When I try to change it to the cd drive it won't stay selected. For the HD... drive it shows the location as 0/0, so I am wondering if somehow that got selected as the drive but there is no such thing on my computer? I tried deleting it but that didn't work. I wasn't having any kind of problem with this until a few days ago. I installed Dreamwaever and Fireworks a few weeks ago but tried uninstalling those and that didn't work either. Please help me. I am so frustrated!!!
